BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a game controller, and more particular to a game controller, which can accurately control the act of a game character.

2. Description of Related Arts

In 1982, the game producer Nintendo developed a game controller for domestic game platform Family Computer (FC) thereof in order to support the famous game Donkey Kong selling. The game controller of the FC uses the Nintendo's patented cross-shape directional key, two action buttons labeled “A” and “B”, a “start” button, and a “select” button. Such as Super Mario Bros, Contra, Double Dragon are contemporary classical game. Characteristics of these games are that the game character only has two or three acts and eight directions of motion. Therefore, the game player who uses the game controller of the Family Computer is easier to control the game character to play game. The game controller of the Family Computer provides a good experience for the game player.

Another classical game is Street Fighter which is marketed later. The domestic game platform Family Computer fails to provide a good experience for the game player because the game platform Family Computer's performance and operation does not support the game Street Fighter to work on the game platform Family Computer. Therefore, the Nintendo develops and produces another game platform called Super Nintendo Entertainment System (SNES), which improves the SNES game platform performance and the SNES's game controller. The game Street Fighter requires six action buttons, so that the SNES's game controller adds four action buttons, labeled “X”, “Y”, “L” and “R”, wherein the four buttons “A”, “B”, “X”, “Y” are arranged in a diamond shaped arrangement, and the action buttons “X” and “Y” are separately arranged at the end of a shoulder side of the SNES game controller. The game player who plays an old game in the new game platform will generally be satisfied with these improvements that are good enough to meet the requirements of the new game, such as Street Fighter. The game controller of the game platform SNES provides a good experience for the game player.

When the 3D game period comes, the type of game controller such as SNES's game controller fails to provide a good operation experience for 3D game. For example, in 3D platform game like Super Mario 64, using SNES's game controller can only allow the game character Mario to move forward, left, and forward-left, but nothing in between. It is a big limitation to the moving control of the game character. Some early 3D games, such as Resident Evil, overcome this limitation by assigning the Left and Right directions on the game controller to spin game character for determining moving direction, i.e. controlling the game character moving by the directional buttons of the game controller. This, however, creates its own problems as the game character is unable to move while spinning, that requires the player to stand in the same spot while changing direction. In early 3D game, the camera position cannot be adjusted, so that some camera positions would affect the game playing.

Sony produces a game controller Dual analog Controller which matches its game platform Play Station and solves the above mentioned problems occurred in the early 3D game. This type of game controller has two joysticks arranged in a symmetrical configuration with the Dual analog Controller on the left thumb position and the face buttons at the right thumb position. The left joystick controls the motion of the game character while the right joystick controls the camera for adjusting the camera position to provide convenience for playing game. The right joystick not only allows camera controlling in a third-person platform game, but also allows the player's gazing and aim controlling in a first-person shooting game (FPS). As opposed to the left joystick, it controls where the player moves. Later, the game controller employs two vibration motors for giving the game player even better experience. Until now, game controller, such as the game controller of Sony's Play Station 3 the game controller of Microsoft's XBOX 360, and etc., has two joysticks.

The drawback of the joystick is that the precision of locating is not enough for some games to the game player. The joystick is also called as joystick potentiometer, which controls the cursor or the sighting in a game through a method of angle determining speed. For example, when the game player pushes the stick to left, the cursor or the sighting moves left, wherein the more angle is pushed, the cursor or the sighting moves more faster. The cursor or the sighting's speed can be configured in the game, but this is a tough choice. If the setting of the cursor or the sighting speed is fast, then the cursor or the sighting moves fast. But, it is not good for accurately moving the cursor or the sighting in short distance. If the setting of the cursor or the sighting speed is slow, it is good for accurately controlling the cursor or the sighting. But, it will spend more time to move the cursor or the sighting to the edge of the screen. Considering the speed and precision of the cursor, one can set a value of the cursor's moving speed to meet the basic requirement of the game. However, the result is that the moving speed and the precision of the cursor both are not good enough. Or, let the game player to change the speed among several speeds which are presetting. But, the changing of the speed needs the game player to operate. Such as double pulled joystick, the game player has to pull synchronously left joystick and right joystick toward back, that will reduce the locating speed of the cursor or the sighting. The requirement of the moving speed and precision of the cursor or the sighting in the game cannot be satisfied in the present joystick at the same time. The present joystick fails to provide a good experience for the game player.

A Chinese patent application number 200810241882.5 has improved on the game controller of FPS game, which comprises a track ball for moving in-game cursor. The trackball has smaller diameter that is limited by its mounting position on the game controller. The displacement of the trackball-rotation is short, which reflects in the game that the cursor moving distance is short. It is good for locating accurately but, if the target is away from the present position of the cursor, the trackball needs to be rotated several times, and thus the aiming speed is seriously affected. If the trackball has a higher sensitivity that, when the trackball rotates a time, the cursor can move longer distance, it's difficult to accurately aim in this condition. Therefore the trackball has the same problem that cannot meet the requirement achieving the moving speed and the precision simultaneously.

Computer is another game platform. In comparison with the domestic game platform, the computer has a different control method, that is through the keyboard and the mouse to control the game character. The advantage of the keyboard and the mouse is to control the game character rapidly and accurately, but the game player requires to have a straight sitting posture that renders the game player to get tire easily, and thus there is no better experience than using the game controller. Using the game controller, you can sit in any posture you like that enables the game player does not feel tire that easy and provides a better playing experience. However, the game controller cannot be rapidly and precisely located.

The right handle 12 is located on the right side of the controller housing 10. The left handle 11 and the right handle 12 are connected at the middle wire of the controller housing 10. The functional buttons are divided into two parts, wherein one is the direction control buttons 111 provided on the surface of the left handle of the controller housing 10, for controlling the moving direction of the game character, wherein another is the action buttons 112 separately provided on the surface of the right handle 12 of the controller housing 10 and on the back surface of the game controller for controlling action of the game character.

As shown in FIG. 5, the management module 30 further comprises a processing module 302 and a communication module 303 linked with each other.

Referring to FIG. 1 of the drawing, the locating device 20 further comprises a displacement sensor 201 and a locating area 202, wherein the locating area 202 is defined on the surface of the right handle 12 of the controller housing 10. At one end of the displacement sensor 201, a securing device 2020 is provided for securing the displacement sensor 201 on a finger wherein the displacement sensor 201 moves as the finger moves in the locating area 202, so as to implement to control the game character action. In addition, the displacement sensor 201 links to the processing module 302, so that when the displacement sensor 201 begins to move, the displacement sensor 201 sends a displacement data to the processing module 302 of the management module 30. The displacement data includes the moving direction and moving distance of the displacement sensor 201.

After the management module 30 of the management module 30 receives the displacement data that is sent by the displacement sensor 201, the management module 30 processes and encapsulates the displacement data and generates formatted displacement data which is identified by the game platform. Then, the formatted displacement data of the displacement sensor 201 is sent to the communication module 303. The communication module 303 sends the formatted displacement data of the displacement sensor 201 to the game platform. Through the game platform, the current place of the displacement sensor 201 would be shown on the display device linked to the game platform.

During the moving of the displacement sensor 201, the displacement sensor 201 continually sends the displacement data of the displacement sensor 201 to the management module 30 and the management module 30 continually processes the displacement data of the displacement sensor 201 and generates the formatted displacement data. The management module 30 sends the formatted displacement data to the game platform, wherein the current place of the displacement sensor is showed on the display device through the game platform. Therefore, the moving path of the displacement sensor 201 can be shown on the display device rapidly and precisely.

When the displacement sensor 201 stops moving, the displacement sensor 201 stops sending the displacement data of the displacement sensor 201 to the management module 30. The management module 30 stops sending the formatted displacement data of the displacement sensor 201 to the game platform, and then the display device shows the position when the displacement sensor 201 stops moving.

When the displacement sensor 201 is in a still condition, the displacement sensor 201 does not send the displacement data of the displacement sensor 201 to the management module 30. The position of the displacement sensor 201 would not change during the still condition of the displacement sensor 201. When the game character moves, the direction control buttons 111 send direction data to the management module 30. The management module 30 processes the direction data, encapsulates the direction data, and generates the formatted direction data, so that the game platform can identify the formatted direction data, and then the formatted direction data are sent to the communication module 303. The communication module 303 sends the formatted direction data to the game platform. The action data is sent by the action control buttons, and that the management module 30 also processes the action data, generates the formatted action data, and sends to the game platform. So that the game controller can accurately control the game character.

The holding device 2020 further comprises two resilient rings, wherein the finger is place between the two resilient rings and held between the two resilient rings for fixing the displacement sensor 201. The holding device 2020 could be an elastic circle too, letting the finger passing through the elastic circle for holding the displacement sensor 201 in position.

A magnetic device is added on the locating area 202 and, at the same time, an iron plate is fixed on the displacement sensor 201, so as to prevent the displacement sensor 201 dropping from the locating area 202. Using the iron made locating area 202 and the magnetic device fixed on the displacement sensor 201 can achieve the same result.

According to a First Personal Shooting (FPS) game, the workable method of the locating device 20 is illustrated. In the FPS game, the locating device 20 controls a weapon cursor of a game character, so that the weapon can rapidly and accurately locate the firing target. Therefore, at the beginning of the game, the weapon cursor of the game character shows in the middle of a display device which is controlled by the locating device 20, and the display device and the game controller are separately linked to the same game platform. The weapon cursor in-game movement is accompanied by the displacement sensor 201 moving cursor. When the displacement sensor 201 starts to move on the locating area 202, the displacement sensor 201 which is scanned in the locating area 202 sends the displacement data to the processing module 302 of the management module 30. The processing module 302 processes the displacement data and generates the formatted displacement data, and then the formatted displacement data are sent to the communication module 303.

After the communication module 303 receives the formatted displacement data, the formatted displacement data will be sent to the game platform. After the game platform processed, the display device which is linked to the game platform shows the position thereof after the cursor has been moved.

When the displacement sensor 201 keeps moving on the locating area 202, the displacement sensor 201 keeps sending the displacement data of the displacement sensor 201 to the management module 30. After the management module 30 processes and generates the formatted displacement data, the formatted displacement data of the displacement sensor 201 are sent to the display device that is linked to the game platform through the game platform linked to the game controller. Therefore, the display device can rapidly and accurately show the moving path of the weapon cursor of the game character used by the displacement sensor 201 controlled. When the displacement sensor 201 suddenly stops moving, the displacement sensor 201 stops sending the displacement data to the management module 30 and the management module 30 stops sending the formatted displacement data of the displacement sensor 201 to the game platform. The display device shows the weapon cursor position and the displacement sensor 30 stops moving the place. So that the displacement sensor can achieve rapidly and precisely controlling of the weapon cursor of the game character being used.

The sliding frame 204 provided on the locating area 202 enables an orientation of the displacement sensor 201 being not changed, that affects the accurateness of the locating. Preferably, the displacement sensor is a photoelectric sensor.

Referring to FIGS. 7 and 8 of the drawings, an alternative mode of the preferred embodiment of the present invention is illustrated, wherein the locating device 20 of the game controller further comprises a displacement sensor 201, a locating area 202 and a sliding frame 204, wherein the sliding frame 204 is mounted on the locating area 202 and the displacement sensor 201 is mounted on the sliding frame 204. Preferably, the locating area has a rectangular surface and two sliding slots 2021 are provided on two opposite side edges of the locating area 202 respectively. The two sliding slots 2021 are parallel and have a length the same as the length of the side of the locating area 202.

The sliding frame 204 further comprises a first guider track 2041 and a movement device is provided at the both ends thereof. More preferably, the movement device comprises at least a wheel for mounting the two ends of the first guider track 2041 in the sliding slot 2021 of the opposite side edges of the locating area 202, so that the first guider track 2041 can move from one side to another side along the locating area 202.

The displacement sensor 201 is provided on the first guider track 2041 in order to move along the first guider track 2041. Preferably, the displacement sensor 201 is a photoelectric sensor. When the displacement sensor 201 moves from a centre of the locating area 202 to a lower right corner of the locating area 202, the displacement sensor 201 moves to a right edge of the locating area 202 along the sliding frame 204, and, at the same time, the sliding frame 204 moves to a lower edge of the locating area 202 along the two sliding slots 2021 of the locating area 202. When the displacement sensor 201 is located at the right edge of the locating area 202 and the sliding frame 204 is located the lower edge of the locating area 202, the displacement sensor 201 is already located at the lower right corner of the locating area 202. The displacement sensor 201 is mounted on the sliding frame 204 in such a manner that the displacement is able to move freely in the locating area 202 and locate rapidly and accurately at any position of the locating area 202.

According to the game supported the different game controller, the game is divided into two types, one just supported keyboard and mouse, the other supported the gamepad. But the game controller of the present invention is supported by the game of above type. It worth mentioning that in order to support above two type of game, the game controller employs three work mode A, B and C, wherein mode A is mouse mode, which also is the default mode of the game controller of the present invention, mode B is analogue joystick mode, mode C is analogue mouse mode. Pressing a function key of the game controller to change above three work mode. If the game only supported keyboard and mouse, the game controller of the present invention works on mode A, if the game only supported gamepad, the game controller of the present invention works on mode B or mode C.

The following utilizes a FPS game as example to illustrate the work process of the game controller of the present invention under above three work mode. In the FPS game, the weapon cursor of the game character used is controlled by the displacement sensor 201. The displacement sensor 201, preferable is a photoelectric sensor.

When the game controller of the present invention works on mode A, the data format which the FPS game can identify as the same as the default encapsulation format of the management module 30 of the game controller of the present invention, so it isn't necessary to process the data, the data can send to the game platform directly. The detail work process as recited above.

When the FPS game only supported gamepad, the game controller of the present invention works on mode B or mode C, at this time, the data need to change format which is sent to the game platform by the management module 30, so that the displacement sensor 201 of the locating device 20 of the game controller of the present invention should control the weapon cursor of the game character used of the FPS game. In fact, the processing module 302 of the management module 30 changes the data format which is sent to the game platform.

The detail process of the data change by the processing module 302 of the management module 30 describes as the following.

The specific definition of the joystick signal of the ordinary gamepad is that: the coordinate axis x and coordinate axis y represent the location of the stick, according to the location of the joystick, the coordinate axis x and coordinate axis y of the stick through analog to digital converted, the digital signal between 0 and 255 is sent to the game platform. According the digital signal to determine the moving direction and speed of the cursor. When the axis x send the data to the game platform between 129 and 255, the cursor of the game moves toward right, the data more bigger the moving more faster, at the 255 the moving speed achieves top speed.

When the game controller of the present invention work on the mode B or mode C, the displacement data of the displacement sensor 201 is changed into the displacement value by the processing module 302 of the management module 30, the displacement value is integer that between 0 and 255. The specific process is that:

The processing module 302 of the management module 30 counts the displacement data of the displacement sensor 201, generated the actual moving value. The processing rule is every eight moving unit records 1, the maximum does not exceed 255.

After that, according to the setting sensitivity of the displacement sensor 201, processing the actual moving value of the displacement sensor 201, generated the displacement value of the displacement sensor 201. The rules of processing the procedure is that: the displacement value of the displacement sensor 201=the actual moving value of the displacement value of the displacement sensor 201× the setting sensitivity of the displacement value. The maximum displacement value does not exceed 255. The setting sensitivity is between 1 and 8.

When the work mode of the game controller is mode B, the displacement sensor 201 simulates the control method of the right stick which controls the weapon cursor of the game character using. When the displacement sensor 201 locates in the centre of the locating area 202, the weapon cursor of the game character using does not move, when the displacement sensor 201 moving, the weapon cursor start to move. In the FPS game, the more the displacement sensor 201 is far away from the centre of the locating area 202, the more the weapon cursor moves faster.

In work mode B, the steps that the displacement sensor 201 simulates the right stick by the management module 30 as following:

Step one, the management module 30 detects whether the displacement sensor 201 is in work state, if the displacement sensor 201 isn't in work state, then the communication module 303 of the management module 30 would simulate the coordinate of the current position of the displacement sensor 201, the axis x value of the right stick=128, the axis y value of the right stick=128, then sent the coordinate value to the game platform; if the displacement sensor 201 is working, the go to next step.

Step two, if the displacement sensor 201 moves towards the positive direction of axis X, then the axis X value of the present position of the displacement sensor 201 would be simulated the axis X value of the right stick, the axis X value of the right stick=the axis X value of the right stick+axis X moving value of the sensor, if the axis X value of the right stick more than 255, then the axis X value of the right stick=255, and go to next step; if the displacement sensor 201 moves towards the negative direction of axis X, then the axis X value of the right stick=the axis X value of the right stick−the axis X moving value of the sensor, if the difference value less than 0, then the axis X value of the right stick=0, and go to next step.

Step three, if the displacement sensor 201 moves towards the axis Y positive direction, then the axis Y value of the displacement sensor 201 present position would be simulated the axis Y value of the right stick by the communication, the axis Y value of the right stick=the axis Y value of the right stick+the axis Y moving value of the sensor, if the summation more than 255, then the axis Y value of the right stick=255, and go to next step; if the displacement sensor 201 moves towards the axis Y negative direction, then the axis Y value of the displacement sensor 201 would be simulated the axis Y value of the right stick by the communication module 303, the axis Y value of the right stick=the axis Y value of the right stick−the moving value of the sensor, if the difference value less than 0, then the axis Y value of the right stick=0, and go to next step.

Step four, the axis X value of the right stick and the axis Y value of the right stick are sent to the game platform, which generated by the displacement sensor is simulated the right stick, then this process is done.

When the game controller of the present invention's work mode is mode C, the communication module 303 of the management module 30 changes the displacement data of the displacement sensor 201 into the data format of the right stick, as the following step:

Step one, the displacement sensor 201 sends the displacement data to the processing module 302 of the management module 30, the processing module 302 judges whether the displacement sensor 201 is moving, if the displacement isn't moving, then the processing module 302 simulates the present position of the displacement sensor 201 to the coordinate value of the right stick that the axis X value of the right stick=128, the axis Y value of the right stick=128, if the displacement is moving, the go to next step.

Step two, when the displacement sensor 201 moves toward axis X positive direction, the processing module 302 is simulating the coordinate of the displacement sensor 201, the axis X value of the right stick=128+the axis X displacement value of the displacement sensor, if the axis X value of the right stick more than 255, then the axis X value of the right stick is 255, and go to next step; if the displacement sensor 201 moves towards axis X negative direction, the processing module 302 is simulating the coordinate of the displacement sensor 201, the axis X value of the right stick=128−the axis x displacement value of the displacement sensor, if the axis X value of the right stick less than 0, then the axis X value of the right stick=0, and go to next step.

Step three, when the displacement sensor 201 moves toward axis Y positive direction, the processing module 302 is simulating the coordinate of the displacement sensor 201, the axis Y value of the right stick=128+the axis Y displacement value of the displacement sensor, if the axis Y value of the right stick more than 255, then the axis Y value of the right stick is 255, and go to next step; if the displacement sensor 201 moves towards axis Y negative direction, the processing module 302 is simulating the coordinate of the displacement sensor 201, the axis Y value of the right stick=128−the axis x displacement value of the displacement sensor, if the axis Y value of the right stick less than 0, then the axis Y value of the right stick=0, and go to next step.

Step four, the axis X value of the right stick and the axis Y value of the right stick are sent to the game platform, which generated by the displacement sensor is simulated the right stick, then this process is done.

When the game controller of the present invention utilizes a FPS game which supported the mouse, the game controller of the present invention as the same aiming performance as the mouse, the aiming speed and accurateness is better than ordinary stick. When the game controller of the present invention utilizes a FPS game which supported stick, the work mode of the game controller is mode C, compare with ordinary stick has two advantage. One is the cursor has rapidly reflect speed. Ordinary stick used analog potentiometer, comprises a base and a control stick, controlling the moving speed of the cursor in the game by the control stick the degree of inclination, the stick is unstable. To control the instability of the stick, usually setting a middle death zone which locates in the middle of the base, the cursor of the game does not move when the control stick in middle death zone. (It is not necessary to need a left stick in the game controller, the game controller could only have right stick to control the cursor.) Only the control stick out of the death zone, the cursor start to move, in this way the aiming time is delay. But the displacement sensor has not the middle death zone, when moving the displacement sensor 201, the cursor also moving immediately. The other is the cursor can change direction immediately during the cursor moving rapidly. When the cursor is moving rapidly, the control stick locates the father away from the base centre, at this time, if the cursor need to move to opposite direction, the control stick need to move a long distance, and the control stick still need to pass the middle death zone, but utilizing the game controller of the present invention, no matter how the cursor current speed, pushes the displacement sensor less than 0.1 mm towards the direction which you wants the cursor moving, the cursor will move follow the direction.

The management system of the game controller of the present invention, comprises:

A processing module 302 and a communication module 303 which links with each other, wherein the processing module 302 process a displacement data, produces a formatted displacement data, so that a game platform can identify the formatted displacement data which links with the processing module 302, the formatted displacement data is sent to the communication module 303; the communication module 303 sends the formatted displacement data to the game platform which is processed by the processing module 302.
